Disk Utility claims Degraded and failed, Raid Admin says its all fine

My company has a server they haven't been able to use. The person who set it up is now gone. I was acquainting myself with the set up. I looked in the Disk Utility of my company's server to see if i could quickly determine the set up of the system and noticed several of the drives said Degraded and Failed
I downloaded Raid Admin to see what I could do about it and it says everything is fine.
Before I tell my company it is OK to begin using the server to house and share major account files I want to be sure there are no problems. They are already using it for time machine back-ups for everyone so I'm loathe to start from scratch right now.

Ok; so there is an Xserve RAID hardware here, though this case does look to be the software RAID that is centrally involved with this and not the hardware RAID.
The next part of the investigation will involve DU, and to determine why your disk(s) here have apparently been configured for software mirroring, and possibly also using what Apple calls "stacked RAID".
You can either add a volume back in for the failed volume and rebuild that and [here is the usual rebuild sequence (HT3305)|http://support.apple.com/kb/HT3305], though if you're not planning to use software RAID (anymore), then you may well end up archiving your data and then issuing a diskutil command to delete the software RAID volume (see +man diskutil+ for an introduction, and look specifically for the RAID delete command syntax there) (or if that should fail), reinitializing your disks and importing from your backup.
I'd suggest having an off-line backup of your data first. Command input, operational errors or volume corruptions that might arise while using DU can have, um, serious consequences for disk data. See the +diskutil appleRAID delete+ command, but I'd also personally want to have an off-line backup of all your data first. RAID command errors and low-level RAID errors can be quite nasty around unarchived data.

Disk Utility gives error and does not rebuild mirrored RAID

After having a HDD fail on a mirrored RAID I replaced the HDD and attempted to rebuild. Disk Utility reports via Console that it can not find an Apple Boot partition to check size and then fails to repair the RAID. Details follow.

I configured this RAID scheme (two two drive mirrors striped together) according to this kbase document: http://docs.info.apple.com/article.html?artnum=304377
As shown in the above "diskutil checkRAID" output I have a failed HDD. So I replaced the HDD with another 160GB cold spare. I added the new drive to the mirror "Mirror_1" also known as disk5 and hit rebuild. Received the normal message that all data on the new drive I was adding would be erased.
I then receive the following error immediately in the Console Log:
Rebuilding RAID "Mirror_1"
2006-12-15 23:50:24.741 DiskManagementTool [375] WARNING: Could not find Apple Boot partition to check it's size, skipping disk5s-1s.
Rebuilding RAID slice "disk4s3"
Just to stem some confusion, the device ID disk4s3 has been used by the system for both the old failed HDD and the new replacement HDD.
The result of this attempted rebuild is I end up with all the data from Mirror_1 on the new HDD but the new HDD is not successfully added to the RAID, therefore Mirror_1 is still degraded and my problem not resolved.
I ran the appropriate rebuild cmd from both the GUI Disk Utility as described and from the CLI "diskutil repairMirror disk5 disk4s3" but no joy.
Any help would be greatly appreciated. This volume houses a large amount of important data including user home directories so while some offline time may be required data loss would not be very acceptable.
Thanks in advance and I will be happy to provide more information as necessary.

I guess doing it in Terminal would fail too:

I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out.

I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out. I am trying to determine what is wrong with the drive.
I need the data on the drive and it won't show up in Disk Warrior. I have tried different Mac's and different USB cords only to find the same outcome. When selected in Disk Utility the information read as such...
Disk Description : WD Elements 1023 Media                      Total Capacity : 500.11 GB (500,105,740,288 Bytes)
Connection Bus : USB                                                               Write Status : Read/Write
Connection Type : External                                                     S.M.A.R.T. Status : Not Supported
USB Serial Number : 575837314135304D36373132        Partition Map Scheme : Unformatted
As the drive shows in Disk Utility there must be some life left in it surely. There is a possibilty that the physical connection between the USB cord and the external drive is damaged but since the drive shows up I believe it's unlikely... before I give it to the pro's is there anything else I can do to diagnose the issue?

Hello,
I have just experienced the same thing!
Although my external drive shows in Disk Utility, it does not show in Finder.
And the Verify/Repair buttons are also greyed out.
Also, although the drive is 2TB. DU shows it as having Total Capacity of only 4.14GB! (Which should be the Free Space).
I was wondering if you solved your problem, & if so, would you share your solution.
I´m afraid to Erase in case I lose all my Data on the drive.
Thanks in advance for your reply!

iphone 4 has no service after replacing screen and updating, phone company says sim is fine. any ideas? thanks

We had this happen with a ipad mini, took it back to person who worked on it, after a week with trying to get it working again, he replaced it. I will agree with the other replies take it back to repair place there must be something inside the phone that if you don't do repair excalty right it messes up all phone functions. Also I would give the repair person a time frame to either get it working or replace it.

Disk repair button in disk utility greyed out and I cant repair my disk

Safari stopped working totally and I downloaded it again but it wont allow me to install it onto the hard drive saying it cant use the software. Disk utility has detected that the disk needs repair but the repair button is blanked out.
Also I have password issues because it wont recognise my master password even though I know what it is. Even though I dont need it now I am sure I will in the future.

Because it can not repair the errors I have started "repair disk". It says "can not unmount Macintosh HD". Even if I have started from the external disk?
So I get my install CD (Mac OS X 10.5) and started from that. I got the same errors with that disk utility.
Can someone tell me, if this are "right" errors or do I have to try more to repair this errors? My computer is running fine.
I am a bit irritated now.
Best regards

Way back in Jaguar Disk Utility would pop up dozens of "advisory" messages of no interest nor meaning to anyone except possibly some programmers. This needlessly alarmed regular users. The same thing is happening again in Leopard. The SUID messages are not meaningful nor are they errors, in effect they are announcements that some list being consulted by the utility says one thing, the actual files say something else, Disk Utility is going to assume there is a reason for actual setting and not going to change it, but you (it's kind of assuming you are the programmer) should know this. If the "Die Zugriffssteuerungsliste" is German for ACL (Access Control List) it is the same deal: an ACL was found, but no one told Disk Utility there was suppose to be one.
If the messages bother you download the whole 110MB 10.5.1 update and run it. It quiets down the output for all the SUID statements save one. Might even shut down the ACL advisories--don't know because I haven't bothered to download 110MBs of updater, I just ran the patch update.

Anyone know Disk Utility, Ignore Ownership, and disk image DL DVD issues?

I am currently having issues with backup DVD's I burned using Disk Utility. I can put the dual layer DVD's in and the system reads them. When I try to pull a file off the Dual Layer DVD a circle with an X appears notifying me that I cannot copy the files to my desk top.
When I check the DVD's permissions it reads Admin (me) read and write with the ignore ownership checkbox checked...which means I should be able to pull files off the DVD. The only way I can currently get information off the DVD is to duplicate the entire disk to a new folder by selecting the DVD while holding down the Cntrl key and selecting duplicate. I have had other issues with DVD's and disk images in Leopard....including having to eject either through disk utility or by selecting the image with the Cntrl key held down. Finder eject, keyboard eject, and the menu eject selections suddenly report that the disk is in use.
The DVD's were burned by creating a dual layer dvd image through disk utility with the read/write option checked.
After duplicating 2-3 disks, the system itself is unable to mount any more disks from the series of backups. When I look at disk utility it reads that the disk is not mountable. I have to restart my computer so the system can continue to read the backups.
My Itunes disk backups are marked the same way (ignore ownership) with admin read/write privlages....I have no problem pulling files off these disks.
I have tried both logging in as root and booting from an external drive...same problem. Is this some nasty Disk Utility bug? Is anyone else having bizarre permission related issues with Disk Utility and Disk Images.

When you create the image in Disk Utility, did you
change the 'Partitions' setting?
If you leave it to read 'CD/DVD', it will create a ISO9660/UDF image.
To be able to maintain permission and extended file attributes, you
need to select 'GUID Partition Map'.
I assume you used iTunes to create your music backup?
It seems it creates the correct image type for you.
Before sending this message, I actually created a single layer image,
copied some files to it and gave additional permissions to other users on my system.
Afterwards I copied the files to my Desktop, verifying that the attributes are still intact.
Best regards
(It took quite a while to burn this 4x DVD-RW Anyways, I hope I could help)

OSX Lion Disk Utility won't verify/repair RAID volumes

SInce I upgraded to Lion (now at 10.7.4) I can't use the Disk utility to verify or repair the disk catalog (disk first Aid) on apple soft RAID volumes. These volumes were created in 10.6 use the Apple RAID feature of disk utility.
I have one striped and one concatenated volume - neither will work. Press the button and the progress bar flashes for a fraction of a second, then nothing. no error, no message in the window - just no repsonse. Works fine on non raid volumes in the same disk enclosure -Firmtek Seritek/5PM, with seritek 2ME4-E sata card.
Not sure I really want to recreate and recopy the drives....
Any ideas? Seaches haven't turned up this specific issue.

A quick search in these forums for permissions or *permissions problem* reveals many posts the past four months.
In a nutshell, repairing permissions w/Leopard takes anywhere from 10-40 minutes, depending on what's installed and what's contained in /Library/Receipts/bom/. The repair permissions operation has changed in Leopard. The stalled progress bar is an unresolved bug (they haven't figured out how to make it work whilst it's checking or rebuilding the a.receiptdb, in /Library/Receipts/db/. To see what's really going on, open that folder in a Finder window, select list view, launch Disk Utility, select your boot volume, and click on repair permissions. Watch the Finder window flash files that are being read and checked against the current a.receiptdb file. That's what's taking all the time and freezing the progress bar. Once that's finished, the progress bar starts moving and the permissions are being checked and repaired. Also note, that you won't get any *they were repaired* message back for any that are noted to be incorrect.

Disk Utility Reports Volume Check Failed

I've been having some trouble with one of my two internal hard drives, so by mistake I ran Disk Utility from the Panther install disk on my PowerPC G5 running 10.4.10...I didn't realize until after I'd run Disk Repair that it wasn't the Tiger install disk I was using.
The Disk Repair Utility from the 10.3 install disk reported an "Invalid Leaf Record Count(it should be 41 instead of 210)". It also said that "2 HFS Volumes Repaired, 1 Volume Could Not Be Repaired". This was particularly puzzling since there were only two partitions on that internal hard drive. What was this other Volume it referred to?
Upon realizing that I was using an old CD, I ran Disk Utility from the Tiger install disk, and got a report "Invalid Catalog Record Type. Volume Check Failed."
Can anyone shed any light on what this all means, and how I can fix it?
Many thanks in advance!
-Zina

Thanks, abrody, for your reply. First, I ws lucky in that there was no indication other than Retrospect reporting a problem with this, the client machine, so all data was available and the system seemed to be working fine (other than the error report).
Here's what worked for me: I ran Disk Repair (from the Tiger install disk)on all 4 partitions on my second internal HD, and came up with a clean report. I erased one of the partitions and, using SuperDuper, I cloned the system partition from the troublesome partition on the other internal HD. Then I ran Disk Repair from the install disk again, on the cloned partition, to be sure I didn't carry over the problem with the clone. It came up clean.
Then I erased the troublesome system partition and cloned the system back over from the trouble-free partition clone.
I ram Disk Repair again from the install disk, just to make sure everything came up with a clean bill of health, which it did.
But I'm going to keep a close eye on this internal HD, since I think it's possible it's failing. I always back up all my data every night, so at least I'm covered there.
Again, thanks so much for your reply and help.

Disk utility doesn't show xServe RAID Array

I have a new (to me) xServe RAID box and I'm stuck, the stays lights are green the fiber link light is green on the RAID and not lit on the PCI card but shows up as green in the fiber link section of the settings tool but the RAID array doesn't show up in Disk Utility so I can't format the drives.
I set up the disks as Enhanced JBOD using RAIDadmin and I've deleted and created it a couple of times, I'm just not sure what else I should try, I've read the manual but. Can't find any suggestions of what's going wrong.
Thanks

If you have tried restarting a few times and it still doesn't show up I'm afraid you are gonna have to go back in and check the connections. I know they just slot into the carriage, but possibly it is not in tight. I can only suggest you open it up and check everything thoroughly. If after a thorough check, if it still does not mount you may want to take the hard drive back and swap it. Are you sure it was only a hard drive failure in the first place? I only ask this because WD hard drives have quite a solid reputation.

HD in Disk Utility is Not Right - Missing RAID Tab

I have totally messed up my HD, and now looking in Disk Utility I don't see the tabs that are normally associated -
When I click on Volume - First Aid and Partition are the only tabs available. No Erase, RAID, or Restore tabs. (picture attached)
When I click on Partition - First Aid, Erase, and Restore are the only tabs available. No RAID tab. (picture attached).
What are the impacts to not having these tabs, especially the RAID tab? How do I get them back? I am sure that this happened when I did an erase and reinstall...obviously not correctly.
Macbook Air -mid 2012. Came with ML, installed Mavericks, installed Yosemite. Long story short, since Aug I have erase and reinstall 3 times. This week I found that I was missing emails in Mac Mail App, and through researching where my lost emails were, I stumbled upon the missing tabs in Disk Utility. for my HD
As for the missing emails, my TM backups have not included a user/library folder since 8/16. This is about the time I did the very first erase reinstall. Last night I restored from TM backup and selected the 8/16 date to use, as my only option in getting those emails back. Of course, the emails missing between 8/16 and yesterday are gone forever. Since I restored using 8/16 I am now back on Mavericks. The restore did not bring these tabs back in Disk Utility for my HD. I won't upgrade to Yosemite again until I can resolve this Disk Utility HD problem.

I've heard that this has something to do with Yosemite. Once you upgrade to Yosemite, it changes disk utility and removes those tabs. From my research, some developers that were part of Yosemite testing saw this during the version tests before public release, and they feel it is a Yosemite bug, not sure why Apple would choose to change this, but maybe they have a product or feature coming in the future that may need a set up like this. It doesn't happen to all computers, just some, and think its directly related to the solid state HD.
I've seen in other posts a Terminal code that some said helped, but I am not sure I want to try that. What if Apple does something in an update somewhere that fixes or changes this as is, and I did the Terminal code now that then further messes things up if/when an update fix comes along.
I don't need to partition my HD, at the moment, so not highly impacted by this. Other than this, the computer is working fine. Its just strange that its now missing.
